Abstract

A method for quantitative determination of glucose, maltose, and reducing dextrins in starch hydrolyzates is described. The components are separated by paper chromatography and determined colorimetrically by measurement of their reducing power with alkaline copper and arseno-molybdate reagents. The probable error of the determinations with the use of this method is about 2%. A compact apparatus was designed, suitable for handling a large number of samples in the chromatographic separation. It is particularly useful for compounds with low Rf values.

纸色谱法测定淀粉水解产物中的还原糖
描述了一种定量测定淀粉水解物中葡萄糖、麦芽糖和还原性糊精的方法。用纸色谱法分离各组分,用碱性铜和钼酸砷试剂测定其还原力。该方法测定的误差约为2%。设计了一种适用于色谱分离中处理大量样品的小型仪器。它对具有低Rf值的化合物特别有用。
